It LOOKS like it's starting up again, fan starts, CD spins, but no display... Doesn't matter whether I'm running X, or from the console. After wakup, nothing seems to work. Fn-F4 will send me to sleep again though... CTRL-ALT-Fx, does nothing...

Anyone know? I've seen reference to people having success, but I've had nothing but bad luck with ACPi & suspending so far.

Hi all.

(Then it's power switch time).

Can anyone give me a hint as to where the kernel should be 
re-initialising the video?
